Although both cases were proceeded concurrently, wrote Feygin on his Twitter account, they cannot be considered identical.

Mark Feygin stresses that Nadiya Savchenko was captured and forcibly taken to Russia, where later Russian authorities accused her of killing two of their citizens. At the same time, both Yerofeyev and Aleksandrov came to Ukraine on their own will, fighting for the illegal Russian-backed separatist organisations.

Ukrainian pilot Nadiya Savchenko was captured in July 2014, she was then kidnapped and taken to Russia. Russian prosecutors accused her of killing two Russian journalists in Luhansk region and illegally crossing the Ukrainian-Russian border. In spite of her denying the charges, Savchenko was convicted and sentenced to 22 years in prison on March 22nd.

On April 6, the verdict came into force, and Savchenko immediately declared a full hunger strike. Numerous world leaders, political institutions, and human rights organisations, among them the E.U. Parliament and U.N. members, call on Kremlin to immediately release the Ukrainian pilot.
